Tact Switches from Würth Elektronik eiSos

#TimetoSwitch

Tact Switches

The Tact Switches from Würth Elektronik are characterized by performance stability and long lifetime. All metal elements are corrosion resistant proven by a 48 hours salt spray test. Polyimide tape or silicone rubber protect the switch even in tough environments. The switch range includes various high quality solutions like dip, rotary, detector, micro, slide, rocker switches and encoder. Available from stock. Samples free of charge.

Product Benefits:

IP67
Long lifetime
High durability
Corrosion resistant metal elements
Full load life cycle test
Tight tolerance due to automated production

Characteristics

The corrosion resistance of all metallic components was tested by a 48-hour salt-spray test.

The snap dome is made of stainless steel to ensure high reliability and reduced friction. The indicated switching cycles have been tested under full load.

Polyimide film provides protection against environmental influences and silicone inserts are used for harsh industrial environments.

The plastic material withstands five times reflow and has been tested for flammability according to UL.

Automated production reduces mechanical deviations and ensures high consistency of mechanical parameters.
